Another factor could be superhero over saturation. Diesmiling mentioned reboot mania and franchises, but there has also been an over saturation of superhero movies in the past few years. I think we will also see superhero movies slowly start to decline in their box office pull. I think gone are the days we see superhero movies pull in 400-500 million domestic. The only one I could see getting close is TDKR and if it does it won't go much over 400. The GA is getting tired of all these superhero movies and they are all competing with each other and bringing down their overall box office pull.
This is a fair point, and to a certain degree, something I agree with.
The single biggest issue is Marvel (no offense, Marvel fans) flooding the market with sub-par films for second rate heroes. Iron Man, Spider-Man, X-Men, Batman, these movies are all beloved. What hurts the superhero genre are movies like Fantastic Four, Daredevil, and Ghost Rider. Movies that were made without passion or care, pumped out to capitalize on the massive success of the first Spider-Man.
If a movie like X-Men: First Class were to underperform, I think the fact that Thor, Green Lantern, and Captain America all coming out the same summer would definitley have something to do with it, which begs an even bigger question (and one of the legitimate reasons I could see ASM underperform): Is 2012 just too loaded?
If you look at 2012, it's an epic slate of superhero movies sure to give every fanboy a wet dream.
The Dark Knight Rises
The Amazing Spider-Man
Superman Reboot
The Avengers
The Wolverine
That's Superman, Batman, and Spider-Man movies all in the same year -- and that doesn't even count the freaking Avengers or Wolverine.
The Dark Knight Rises is safe, IMO. It's the final chapter in a big trilogy, coming off the heels of one of the biggest movies ever. People in the general public already know it's the last one, and already know Anne Hathaway is Catwoman. It's the kind of movie that will sell itself, and I would guess the quality will be strong enough to sustain it at the box office. It won't get TDK numbers, but as good as that movie was, getting 500+ million was a bit of a perfect storm that (sadly) factored in the death of one of the stars giving an incredible performance.
I think The Amazing Spider-Man will be fine too. I think it's possible that chaseter is right that it won't gross quite as much as the previous films, but there's no way it has Batman Begins type numbers -- I'd be shocked if it got under 300+ million. Movies that are the safest at the box office these days are franchises that are popular with kids. Despite Batman's epic resurgance, I assure you, Spider-Man is hands down the number 1 superhero with children. The movie will be very successful.
Superman is the most interesting case, by far, IMO. In many ways, he's the "original" superhero, and arguably still the most recognizable superhero in history. That said, there's no question Batman and Spider-Man have easily surpassed him in popularity, and the real question is whether there really is any interest in a Superman movie by current audiences, or if Superman Returns got lost in the shuffle of a crowded summer and turned off those who did go to see it. Releasing the film in the Holliday season instead of the summer is a brilliant move, IMO. It's exactly what Superman will need to stand out among a crowded superhero year. The two pressing questions are A) does the public have interest in a superhero movie and B) what will Zack Snyder and co. turn out, and how will it look/be perceived? With Nolan, we kind of know what TDKR will be. We don't know what Marc Webb's Spider-Man will entail, but we know enough about the producers and those involved (and have seen some set pics) to have a rough idea of the direction they're going with it. I have no idea what they're going to do with Superman, and how the first trailers come off will be EXTREMELY important to its success.
Avengers will be a hit, but the scale of the hit is a questionmark. Definitley the kind of movie that would benefit from being THE superhero movie of the summer and that might suffer from having Batman and Spider-Man stealing it's hype/thunder. Not something Marvel fans want to hear, but I think the superhero team-up idea isn't the explosive unmissable concept some do. Robert Downey Jr. should be front and center with the marketing. (I reserve the right to revise this assessment should Thor and Cap'n America exceed my expectations.
I don't even know when The Wolverine is going to be released, but I suspect it's the one that's going to take the biggest hit. A) I DO think that Gavin Hood's poorly recieved film hurts this one. "Another Wolverine movie? The first one sucked" will be uttered by many a common fan. B) It appears on the surface to be the least original and will be the easiest to skip, in between the final chapter in a Batman saga, Spider-Man and Superman reboots, and the Avengers.
Somewhat off topic tangent over.
